STIRRUP OR HANGER FOR FLOOR-BEAMS.

SPECIFICATION forming part of Letters Patent N 0. 666,918, dated January29, 1901.

Application filed May 17,

To all whom t may concern:

Be it known that I, JOHN A. BUTZ, a citi- Zen of the United States,residing at Pittsburg,

in the county of Allegheny and State of Pennsylvania, have invented ordiscovered certain new and useful Improvements in Stirrups or Hangersfor Floor-Beams, of which improvements the following is a specification.

The invention described herein relates to certain improvements instirrups or hangers for floor-beams and blanks therefor; and theinvention consists in so cutting or shearing a piece of sheet-steel asto produce a blank which by the subsequent bending or folding of certainparts is transformed into a light but strong hanger or stirrup.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification,Figure l is a plan view of my improved blank. Fig. 2 is a perspectiveview of a partially.- folded blank. Fig. 3 is a perspective view of acompleted hanger or stirrup. Figs. 4 and 5 are views similar to Figs. 2and 3, illustrating a modiication. Fig. 6 is a View, partly in elevationand partly in section, of the stirrup or hanger shoWn in Fig. 3, theplane of section being indicated by the line VI VI, Fig. 7. Fig. 7 is asectional view of the same on a plane indicated by the line VII VII,Fig. 6. Fig. 8 is a plan view illustrating the manner of cutting theblanks from a continuous strip of metal of a Width equal to or greaterthan the length of the blank. Fig. 9 is a plan view illustrating themanner of cutting blanks from continuons strips of a Width equal to orgreater than the Width of the blank; and Fig. 10 is a View similar toFig. 9, showing the manner of cutting the blank for the form of stirrupshown in Figs. 4 and 5.

In the practice of my invention the blank is made of a width equal orapproximately equal to the combined Widths of the body or k Wall of thestirrup and of the side Wings of. At one end the blank is providedtongues 2 and 3 in line with the portion ed to form the back Wall of thestirand Vrith one of the portions 4 adapted m one of the side walls ofthe stirrup, .ngue 2 being made of a Width approxiy equal to the portion1, which forms 1900. Serial No. 16,960. (No model.)

the depth of foot or supporting-piece desired in the finished stirrup.lThe tongue 3 is made of a length sufficiently greater than the width ofthe back plate to permit of its end being turned up outside of the otherside Wall of the stirrup. These tongues are separated by a cut on theline a ofthe bend made in the blank to form the sides of the stirrup. Asit is not necessary nor desirable that the sides 4a of the stirrupshould be made full Width at their upper ends, diagonal'cnts b are madein the portions 4 of the blank, said cuts extending from the edges ofthe blank to the junctions of the lines to fold ct and the line of foldc at the upper end of the portion l of the blank.

In forming the stirrup the tongue 2 is bent so as to stand at a rightangle to the portion l to form foot 2a, and the portions 4 are folded onthe lines a to form the side Walls 4aof the stirrup. The tongue 3 isthen bent under the foot 2a and its end up around against the oppositeside Wall 4a, to which it is secured by rivets. Thus it Will be seenthat the foot 1a is reinforced by a piece of metal integral at one endwith one of the side walls and securely fastened to the other side Wall.

To form the hook of the hanger or stirrup, the side portions 5 of theblank are folded over onto the portions 1 and 6 of the blank. Theportion 6 and the folded portions 5 are next bent on the line c and alsoon the line d, thereby forming the hook Which engages the masonry of theWall or the beam, which supports the floor-timbers. It is preferred whenthe stirrup is to be used in connection with brick orv stone Walls tobend the outer .end of one of the portions 5 up and the ends anchorageobtained by folding both portions 5 over to form part of the hook, asdescribed, is desirable When the hook is supported by masonry, one ofthe portions 5 may be omitted, as shown in Figs. 4 and 5, Withoutreducing the strength of the Astirrup at the bend beyond a safe marginof safety, and the outer IOO end of the portion 6 may also be omitted,as there is little strain on the downturned portion of the hook.

It is characteristic of my invention that the stirrup or hanger is soreinforced at points of greatest strain as to have a very large marginof safety. and it is also characteristic of the invention that thestirrup and its reinforces are so arranged and proportioned that theblank can be cut either transversely or longitudinally from a sheet orstrip of metal without any loss, except perhaps the extreme inner endsof the portions 5, which it is preferred to cut oif, as the sharp pointsmight infiict injury during the bending of the blank.

I claim herein as my invention- 1. A blank foi stirrups or hangers,consisting of a body portion and side portions, independent tongues inline with the body portion and one side portion, a hook-forming portionin line with the body portion, and a hook reinforcing portion adaptedwhen folded onto the hook-forming portion to extend down onto the bodyportion, substantially as described.

2. A blank for stirrups or hangers having a width equal to the combinedWidth of the back and sides of the hanger, and of sufiicient length toform the body and hook of the stirrup and having at one end tongues orextensions of different lengths, the sides of the blank being cutdiagonally, said cuts extending from the edges to the line on which theblank is bent to form the hook, substantially as set forth.

3. A hanger or strip consisting of a boxshaped body portion, a footportion formed by bent tongues integral with the back and one side ofthe body, the side tongue extending up onto the opposite side and a hookportion integral with the back Wall of the body, and reinforced by alateral extension of the hook folded down onto the same and extendingdown onto the back wall of the body, substantially as set forth.

4. Astirrup or hanger consisting of a boxshaped body portion, a footportion formed by bent tongues integral with the back and one side ofthe body, the side tongue extending up onto the opposite side, and ahook portion integral with the back Wall of the body and reinforced bylateral extensions of the hook folded down onto the saine and extendingdown and riveted onto the back wall of the body, the outer end of one ofthe extensions being bent up to afford increased anchorage,substantially as set forth.

ln testimony whereof I have hereunto set my hand.

JOHN A. BUTZ.
